I was hoping to get a little more information about a stroker build that I'm planning. I bought a spare m42/g240 and I know I need a m47 crankshaft, but I'm not sure if the engine I get it from would matter. I've seen the e46 and e39 crankshaft. I'm just not sure if either is acceptable.
I plan on boring the block to 85mm because further down the road this engine will be turbocharged. I'm looking into getting aftermarket forged internals. Would my rods have to be longer to compensate for the longer stroke?
In terms of CR I would like to keep it at 9:1 or possibly 9.5:1 would this be too much if I eventually go turbo?
Also, does anyone have any good links for a designing a crank girdle?
